Abstract

The assembly for the production of corrugated pipes, with lateral ribs, has a mold with half-molds (16) which travel along adjacent guide paths. The guide paths form a common molding stretch, together with return stretches and two path deflections. At the path deflection points (22,24), deflectors (26,28) have a guide edge (40) in a klothoid loop structure of an upside down tear. The assembly for the production of corrugated pipes, with lateral ribs, has a mold with half-molds (16) which travel along adjacent guide paths. The guide paths form a common molding stretch, together with return stretches and two path deflections. At the path deflection points (22,24), deflectors (26,28) of a low wear plastics material with an integrated lubricant each have a guide edge (40) in a klothoid loop structure of an upside down tear. The guide edge has two klothoid sections (46,48) connected by a curved arc section (50). The deflectors are linked to a compensation unit (60) to smooth out the tolerances of temperature and/or movement speed along the guide path, using a Fluid Muscle MAS 0010NH (RTM) compressed air and air spring system (62).
